Testing the Cherry Hypothesis: Don Cherry of Coach's Corner has said teams that fight more win more (e.g. here). Is that true? It appeared to be on February 18, 2012, the date of the above clip, but a better test would look at the hypothesis' predictive power for data Cherry has not observed (i.e. data after February 18, 2012). Below is a plot of points per game against fights per game, and it is updated daily to reflect data from the 2012-2013 season. I included a standard linear-regression line, and the equation near the top gives the number of points per game a team can expect given how many fights per game it has. '(S)' means fights per game is a statistically significant predictor (at .10 significance level), and '(NS)' means it is not.

College Football

I have rated all FBS football teams and their offenses and defenses using points. I also rated each FBS team's rush offense, rush defense,
pass offense, and pass defense using yards per game (which are good predictors of points) through December 15, 2013. The results
are
here.
The segments represent 95% confidence intervals, which are a measure of uncertainty. The narrower the
confidence intervals, the more confident we can be in the estimate.
